Engine And Engine Cooling Problems of Toyota Tundra - part 2

Several situations where the throttle hesitates when entering traffic or trying to come to interstate speeds on merge ramps. 1-2 sec delay has caused potential close calls while merging, when plenty of room existed to merge at speed.

Approximately 10 minutes into an ordinary drive home from work, the engine abruptly began making extremely loud noise, as if metal or bricks were being thrown inside the engine. Within moments, the engine rapidly lost power and then completely shut down. At no time did any warning lights, engine lights, or malfunction indicators appear on the dashboard prior to or during the failure. This incident represents a serious safety hazard. This vehicle is my primary tow vehicle for transporting a horse trailer, and had this failure occurred while towing, I would have had no control, no engine power, and no ability to maintain speed, creating a high risk of a major collision or highway accident. The fact that the failure occurred with zero warning makes the danger even more significant. Toyota has confirmed that this engine failure falls under the active recall. Despite this, the mode of failure—sudden shutdown while driving without any alert—poses a severe and immediate safety risk to drivers, passengers, and the general public.

I periodically have throttle lag issues when starting to roll and take off from a stop - a lot of times this is in the middle of an intersection or pulling out into traffic lanes. The throttle almost doesn't respond or drops and then a few moments later takes off trying to make up for the throttle lag.

Throttle lag out of nowhere which puts me and family in danger in random times.

Vehicle lost power and wouldn’t speed up while I was on the freeway and nearly caused a wreck because I couldn’t get the vehicle up to the speed limit. I pulled over and after shutting the vehicle off for an extended amount of time I then restated my truck but still experienced a lag in the engine. I would press the gas pedal and it took a while for the engine to seemingly engage and take off. The dealer was notified and they stated “we know of the issue but there is no fix, no need to bring it in as we are aware of the issues”.

When trying to pull out into traffic from a stop there is a hesitation at times. I go to press on the accelerator and the truck does not always move. There seems to be a delay at times. Seem dangerous when pulling out into traffic. It has happened multiple times. No sure if it is the transmission or what.

I've had a recall procedure done to correct an acceleration hesitation, but the problem still persists. When accelerating from a stop into traffic there is a significant acceleration pause before the pickup actually accelerates. I've had several close calls to being hit by oncoming traffic because of the inability to merge into traffic as planned due to the acceleration pause. The pickup currently has just over 56,000 miles on it.

When making a left turn or pulling off from stop light the truck almost stalls out. Very dangerous when traffic is coming. Need a fix ASAP. Could cost people their lives.

Was driving with flow of traffic and the engine lost power went to zero rpm check engine light came on. It’s a non hybrids motor. Wouldn’t turn over once pulled on side of road check underneath engine bay for leaks of fluid nothing was leaking.

On 11/28/2025 I was driving to work and all the warning lights on my 2024 Toyota lit up and the engine shut completely off. I had the vehicle towed to performance Toyota dealership in bountiful, ut. I learned that there is a recall for the engine on these vehicles. The vehicle is still under factory warranty and had 34k miles on it. After a week of my truck sitting at the dealership they still are waiting on a decision from “corporate” on whether they want to replace the engine under the factory warranty or they want to replace the engine under the recall which they are saying “no remedy” has been put out on the 2024 Tundra recall yet. The outcome of either remedy is a new engine. I also asked about just trading the truck in for a newer model which when I asked they took the blue book trade in value down $10k since it had a recall on it. This is no fault of my own and this is terrible customer service from Toyota. I also received a loaner car from them which I cannot drive because I don’t meet the age requirement so my dad has to drive the loaner vehicle which he is very unhappy about since I’m having to borrow his new vehicle to drive back and forth to work and putting miles on his new car. This whole process is very frustrating and unfair to not have a decision made on the engine replacement or being treated fairly on a trade in. Thankfully there was no accident with injuries.

While starting to accelerate from a stop whether it is going straight or turning the truck hesitates and takes multiple seconds to start accelerating leading to a potentially dangerous situation especially when turning and you can't get out of oncoming traffics way. Also when at a slow roll trying to accelerate the truck just does not apply any power for multiple seconds delaying movement and potential to avoid an accident.

Very often when I go to press on the gas, there is a noticeable lag before my truck goes. When there is oncoming traffic it is to a point where I do not try to go in case it lags and could be dangerous. This seems to be a common problem when I talk to other owners of the same model truck.

Throttle lag happens quite frequently. Transmission issues dumping into gear stalling at times delayed start. Dealer says it was normal.

My 2024 Tundra with 33000 miles is part of the latest recall, I called the dealership and was told I got to wait ( wait for what a xxx accident to happen) until Toyota sends me a letter and then dealerships get the parts! my truck is ticking, and not even running rite and no parts to fix it? does anybody know how dangerous this is? xxx I drive myself and family in a $70000 truck that can literally blow up and cause a severe deadly situation especially living in southern maine, and instead of fixing it rite away I gotta wait months from the sound of it. . No letter, no parts, no loaner, just prayers that god is with us until this xxx is fixed. . Sad thing people with a brain know how dangerous it but nobody offers xxx.

When accelerating from a stop the truck stumbles and does not take off. This is dangerous as people may run into you. I have asked many times at dealership if there is a fix yet and the answer is no.

Hesitation and throttle lag when accelerating the vehicle from a slow speed.

Vehicle experiences lag or hesitation from stop.

When completing a slow down, when going to accelerate there is a noticeable delay in the engine responding and before actual acceleration. This typically results in the need to press the pedal hard and suddenly it finally accelerates and at times spins the tires, almost uncontrollably. This has caused many near misses when trying to cross oncoming traffic, or entering traffic of a busy road or hwy. There have been no warning lights or indicators of any issues. This can be repeated on demand and even the dealership service tech has felt and acknowledged it. It is a common issue across the gen 3 Tundras (2022+) models as found across many forums and owners.

I experience delayed throttle response and throttle lag daily. Acceleration is unpredictable. The vehicle barely moves in some cases when pressing the gas pedal. Other times, the tires will chirp. The vehicle will sometimes hesitate so long to accelerate, that I've almost been t-boned and I've held up traffic. It seems like the truck thinks I'm going to run into something, even when there's nothing in front of me. The delay is sometimes 3-5 seconds before it will allow any acceleration. This seems like a huge safety issue, not being able to get out of the way of oncoming traffic and having such an unpredictable, and often delayed throttle response.

On several occasions I have a dead pedal situation on acceleration from a brief stop. When you press the accelerator, the truck does not accelerate immediately. Instead there is a second or two pause before truck responds to accelerator input. When crossing traffic, this hesitation has caused several situations in which I have almost been t-boned.

Throttle lag. When stopped at a stop sign, I attempted to accelerate and when I pressed the pedal, the vehicle didn’t respond. I had to release the gas pedal, wait a second, then attempt to accelerate again. This time it responded.

My 2023 Toyota Tundra has an intermittent issue where the throttle lags or hesitates when accelerating from a complete stop. The problem occurs unpredictably and causes the truck to fail to respond when pressing the gas pedal. The issue appears to be related to the engine or throttle response system, and the vehicle is available for inspection upon request. This malfunction puts my safety and the safety of others at risk because the hesitation can occur while turning left across traffic or merging into traffic, leaving the truck momentarily stalled in the path of oncoming vehicles. The problem has not yet been officially reproduced or confirmed by a dealer or service center, but it has happened multiple times under normal driving conditions. The vehicle has not been inspected by the manufacturer, police, or insurance representatives at this time. There were no warning lights, messages, or other indicators before or during the hesitation; it happens without any prior notice.

Throttle lag/hesitation when starting from a standstill. Same also occurs when slowly going up a hill, letting off throttle and then back on throttle - engine no response and causes vehicle to roll backwards before engine/transmission catch on again. No service center has looked at this issue yet.

I was driving my 2023 Toyota Tundra when the engine shutdown while going 55mph, the speed limit. Truck shutdown as I approached a long, curvy hill, felt like I was in great danger and any vehicles around me. There was no warning, had no idea what was going on. Took vehicle to dealership, after 24 hours I went back to dealership to check on it. Was told they didn’t look at it because they knew the engine was bad, needed replaced. There is a recall for this and was told there is no remedy yet. Also, they say they don’t have a vehicle for me to drive. I paid $65000 cash to have a vehicle to drive and keep me and my grandkids safe, now nothing!.

While driving under normal conditions, my 2023 Toyota Tundra trd pro hybrid experienced a sudden and severe loss of propulsion. The vehicle abruptly entered fail-safe (limp) mode and would not accelerate beyond approximately 5–10 mph. This occurred without warning and created an immediate safety hazard in traffic. Multiple warning messages illuminated simultaneously, including: hybrid system malfunction, check engine, Smart stop system malfunction, and advanced ultrasonic detection malfunction. The hybrid system effectively shut down and the vehicle could not maintain normal road speed. I brought the vehicle to a Toyota dealership. The dealership performed only ecm and hybrid ecu software updates and cleared codes. No mechanical inspection, oil pressure analysis, particulate inspection, turbo system evaluation, hybrid motor synchronization testing, or engineering-level diagnostics were performed. Toyota corporate subsequently stated that the software update was the “final” resolution and declined further diagnostics. I was advised to return to the dealership if the issue reoccurs. This failure mode matches the documented loss-of-propulsion behavior described in Toyota’s v35a engine machining-defect recall (sudden power loss, limp mode, cascading system failures). Hybrid models are currently excluded despite using the same engine platform and exhibiting identical symptoms. Sudden loss of propulsion at road speed presents a serious crash risk. This appears to be a safety-related defect that is not being adequately investigated or remedied for hybrid models.

The truck “detected” a warning collision when there was no one in front of me which made the engine lag. There for causing me to come to an abrupt stop from 40 mph. I stepped on the gas to get back up to speed with traffic beside and behind me and there was no power almost causing an accident. This is the 3rd time this truck has done this in 6 months.

Over the course of ownership I have had frequent instances of loss of power and/or lack of acceleration resulting in almost stalling out while trying to take off. This causes dangerous situations when trying to pull out into traffic because you never know when the vehicle might hesitate and crest unsafe distances between you and other moving vehicles.

Just asking for an investigation. Same engines in vehicle year 2023 gas only models have been recalled for safety because the engine locks up while driving causing a this safety issue. My model year is 2023 and is a hybrid but has not been added to the recall. The hybrid should be included in the recall as well since it is the exact same engine. This is a dangerous situation for me and my family as well as others I am on the road with.

I was driving on the highway at 55 mph when my engine suddenly began making a loud knocking noise and lost power. I immediately pulled over, but as I was doing so, the vehicle lost all power and the engine light came on. This was a dangerous situation because I was in the middle of traffic and almost got rear-ended as I couldn’t keep up with the traffic speed. Let alone the warning light didn’t come on until I lost all power to the engine. This is a 2023 hybrid limited with under 15,000 miles! I could not believe it as I just got rid of my 2022 Tundra limited with engine issues and purposely got a hybrid to avoid engine problems. Toyota, what on earth are you doing?!.

Toyota has just extended the engine recall for debris left in it thru the 2024 year model for all non-hybrid Tundra vehicles. This recall makes no sense the hybrid vehicles have the exact same engine and therefore have the exact same safety issue. The claim they are not being recalled because they can still be powered by the hybrid system, but this is false. If the engine seizes from this debris it will render the vehicle inoperable and cause a safety issue too. Those with the hybrid who have experienced the failure confirm the vehicle becomes inoperable. When they take it to Toyota if still under warranty they are only offered a short block rebuild and not the long block and turbos as all non-hybrid receive under the recall. Please look into this issue and force Toyota to extend the recall to both hybrid and non-hybrid as they both have the same engine and pose the same safety risk to the driver and other vehicles on the road.

Vehicle randomly stalls or experiences throttle lag/acceleration hesitation particularly when trying to accelerate quickly through intersections and while turning. Almost seems as if the vehicle loses power all together and then quickly comes back.

Engine maintenance bearing failed at highway speed. I was able to coast to the roadside because there was no other traffic. Engine would not restart.

Throttle body stopped working car went in to limp mode on high way randomly multiple times till it finally just gave out randomly again on highway. Could no longer drive had to drive at 5mph to nearest dealer.
